Automatic firearm having an inertial automation system

Abstract

The invention relates to mechanisms for cocking an automatic weapon. An automatic firearm having an inertial automation system comprises a breech, a barrel, a bolt support with a bolt, a recoil spring and a return spring, a trigger mechanism, an ammunition supply mechanism and a bolt support latch. The latch fixes the bolt support in a rear position and is controlled with a trigger. A shot is produced at the instant the bolt support arrives in a front position. A mechanism for supplying cartridges to a cartridge chamber makes it possible to load the weapon when the bolt support is fixed in the rear position. Stable operation of an inertial automation system is achieved.

Claims

1. An automatic, self-loading firearm an inertia-driven system comprising a firing mechanism housing (1), a barrel (3), a bolt support (4) with a bolt (5), a bumper spring (6) disposed between the bolt support (4) and a front wall of the firing mechanism housing (1), between the bolt support (4) and the barrel (3), or between the bolt support (4) and the bolt (4), a mainspring (7) disposed between the bolt support (4) and a rear wall of the firing mechanism housing (1), and a clip latch controllable by a trigger guard of the firearm for fixation of the bolt support in a backward position, WHEREIN the bolt support (4) is forced backward when a trigger of the firearm is cocked, which also compresses the mainspring (7) and causes it to bounce forward, prompting the bolt support (4) to move forward to feed a cartridge and place the bolt (5) in its original position, and when the trigger is activated to make a shot, the bolt support (4) collides with the front wall of the firing mechanism housing (1) via the bumper spring (6), said bumper spring forces the bolt support (4) to bounce backwards which unlocks the bolt (5) that releases the fired cartridge, causing the trigger to be cocked, and compressing the mainspring (7); said compressed mainspring (7) bounces forward pushing the bolt support (4) forward to feed a second cartridge and restoring the bolt (5) to its original position and ready for another shot.

2. The automatic, self-loading firearm of claim 1, further comprising a cartridge feed mechanism and a bolt locking mechanism, and wherein the bolt support is fixed immovable in a backward position.

Description

(1) As an example, the FIGURE demonstrates the design with the bumper spring between the bolt support and the front wall of the firing mechanism housing and the mainspring between the bolt support and rear wall of the firing mechanism housing.

(2) The invention is illustrated with the drawing (see FIG. 1). The firing mechanism housing (pos. 1) includes the clip latch (pos. 2), barrel (pos. 3), bolt support (pos. 4) with bolt (pos. 5). There is the bumper spring (pos. 6) fixed to the bolt support. There is the mainspring (pos. 7) installed between the bolt support and back wall of the firing mechanism housing. The operation principle of the design is similar to that described above.
